"What very popular and hyped book in the blogosphere did you NOT enjoy and how did you feel about posting your review?"
In my opinion, usually books are hyped about for a good reason. And at the moment, I can't even think of a single book that I have not enjoyed! Not a one that has been hyped about that I have read haveI not liked it. But if I were to not like a book that's been hyped about, when I reviewed it I would stress the fact that just because I didn't like it doesn't mean that someone else won't. And I would also try and explain why I didn't care for the book too.
